I am trying to trace the birth of my ancestor David Walter Morgan around1734.According to his Cambridge University graduation record his father was William of St.Georges,Southwark.He went on to become Priest in Ordinary at the Chapel Royal,Westminster and after his death in1795 he was buried in Westminster Abbey.He was also Rector of Little Leighs in Essex a position obtained for him by the wealthy Olmius family.I have been unable to find to trace his birth or uncover any connection with the Olmius family.If anyone is able to look up parish records for me I would be extremely grateful and would,of course,reimburse any expenses.Would the place to look be the London Metropolitan Archive ? I have looked up some Southwark records on-line but have failed to find anything.He was married in 1758 at St.Martin in the Fields.I believe this is Westminster and their records for this period can only be accessed by visiting their record office.
